Issues w/ `lib/libTestPass.so` #1

Closed maxvonhippel closed 3 years ago

maxvonhippel commented 3 years ago

Hi, thank you for making this interesting tool! I am trying to get it to compile and run, but I can't figure out how to make libTestPass.so work, including when I recompile it myself.

Here is my Dockerfile, so you can reproduce my exact setup:

# Set up the system

# Compile it

Compile the Dockerfile like this:

sudo docker build . -t saver

Then run the demo like this:

sudo docker run --rm saver \
        ./SaVerECS -m 100                                   \
                   -t 0.2                                   \
                   -d 0.001                                 \
                   -u 10                                    \
                   -l 5                                     \
       --time-horizon 3                                     \
               --goal "x>=5 & y>=3"                         \
         --plant-file "benchmarks/thermostat/thermostat.ha" \
    --controller-file "benchmarks/thermostat/thermostat.c"  \
                   -o test.smt2

Here is the output:

sudo docker run --rm saver \
    ./SaVerECS -m 100                                   \

SunandanAdhikary commented 3 years ago

Might be an LLVM installation issue. Other parts are compiling properly but the C to SMT conversion is not happening as shown in the 2nd point of the example given in readme. Make sure by running opt command that you have clang-LLVM 7.0.0 properly installed in your system. You should also run our another subproject that we use to generate such LLVM passes like libTestPass.so and convert C codes to SMTLIB2 expressions.

  1. I can see the opt command is not found written in the log but the SSA statements are generated while running the model. So guessing you have worked that out nicely. If not, try running the other subproject I referred to earlier.
  2. Also I can see, in your controller code you have x and w as states i.e. state_x and state_w whereas the plant .ha file has temperature as the state variable. So in controller code it should be state_temperature. Refer to the benchmark.
  3. And you can refer to the logs in the output folders inside each benchmark folder to find out how should the SSA statements corresponding to the controller code look like and also where the .smt2 files should be generated. .json files are generated in the same folder.
rajgurung777 commented 3 years ago

Dear Max, I suggest you do an independent build of the project https://github.com/saverecs/CProgramToSMT. Follow the instruction mentioned in the project on "How to build" and "How to Run". Once these steps are successful you will be able to generate the "libTestPass.so" and so the main project SaverECS will be able to run the function generate_ssaFile() (https://github.com/saverecs/SaverECS/blob/master/src/coreSystem/controller_program/controller_parser.cpp) with no error. Now I still see that you have two errors "clang not found" and "opt not found".

Once again let me suggest you follow the step in https://github.com/saverecs/CProgramToSMT by making sure you have installed clang/LLVM version 7.0.0. Good Luck

maxvonhippel commented 3 years ago

Hi All, thank you for your help.

I have forked the CProgramToSMT repository, and I got it to compile successfully, using LLVM 7.0.0 and Clang 7.0.0. You can find my fork here, and if you'd like, you can reproduce my setup by cloning it, entering the fork, and then running make deps && bash setup_llvm.sh && make build. And indeed, it seems to work. Here is an example, on the thermostat benchmark.

Now I am working on trying to get SaverECS to work, with my LLVM pass. I forked SaverECS here, deleted all of your CMake cache data and files that were particular to your build system, and wrote a Makefile. I will update you on my progress soon.

Thanks a lot, Max. You can initiate a pull request as well if you want.

maxvonhippel commented 3 years ago

Yep, I'll cut pull requests to both repositories once I have the SaverECS working too. Hopefully I'll get it done in the next week or two. Thanks!

I got SaverECS working. The main issue was that the bash code run from C++ would default to /usr/bin/clang instead of my locally compiled v7.0.0 clang, and the same issue for lli and opt. I will cut a pull request soon, where I provide a simple sed command to fix this on your system, in my Makefile. Thanks for all the help!

Great work.

Thanks Best wishes, Amit
